Ironpaw Chef

Because I want to cook every mob in the game...

Assuming you start from 200 recipes pre-MoP, this can be obtained as early as 575 Cooking. There are 20 recipes off the trainer, most of which are part of the Pandaria cooking level path (Blanched Needle Mushrooms, Boiled Silkworm Pupa, Dried Needle Mushrooms, Dried Peaches, Fish Cake, Golden Carp Consomme, Green Curry Fish, Peach Pie, Pearl Milk Tea, Perfectly Cooked Instant Noodles, Pounded Rice Cake, Red Bean Bun, Rice Pudding, Roasted Barley Tea, Skewered Peanut Chicken, Sliced Peaches, Tangy Yogurt, Toasted Fish Jerky, Wildfowl Ginseng Soup, Yak Cheese Curds).

After that, you start getting Way recipes. Each of the 6 Ways has 5 recipes: 1 Tier 1 food, 1 Tier 2 food, 2 banquets (10 and 25 man), and 1 Tier 3 food. If you are leveling the Ways roughly equally, you'll have 226 recipes with the Tier 1s (available after completing the start quest for each Way), 232 recipes with the Tier 2s (550 in each Way), and 244 with the banquets (requiring 575 in each Way). Obviously, that's more than the 240 needed for this achievement, so you'll get this one taken care of with only 575 in 4 of the 6.

If you weren't quite at 200 recipes pre-MoP, you'll easily make the up the difference as you push to 600 in all 6 Ways. By the time you've gotten all the Way recipes, you'll have this achievement even if you started the expansion with as few as 190 recipes. There are also a couple Anglers reputation recipes if you need an extra edge beyond even that. This is, in short, a much easier target than Iron Chef was (250 would have been more the equivalent). Happy cooking!

ok there's a bit of confusion about this achievement, if you have not learned 200 pre-MoP recipes yet, the MoP recipes that you learn at halfhill will not make your counter go up on your tracker but they still count towards the cooking recipes achievements, once you have learned 200 pre-MoP recipes you will get (Iron Chef) and your counter will jump to the actual total amount or recipes you have including MoP recipes
